It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The rate of change of the apparent diffusion coefficient for cementitious mixtures containing pozzolans or blast-furnace slag is typically different than that for mixtures ast, only portland cement. The apparent diffusion coefficient determined by this method includes bound chloride, so proper use of the apparent chloride diffusion coefficient to predict chloride ingress requires consideration of chloride binding.

This calculation procedure is not applicable to specimens exposed to chloride ions during cyclic wetting and drying. Therefore, apparent diffusion coefficients obtained at early ages may not be representative of performance in service. The concentration and valence of other ionic species in the pore fluid also influence the rate of chloride diffusion, and therefore, the apparent diffusion coefficient as c156 by this test procedure.
No other units of measurement are included in this standard.

If you need more info or have any questions, please note the Lab ID number and contact us at: ASTM C states that each sample consists of at least two 2 specimens. The calculation procedure described in C is only applicable to specimens exposed to a sodium chloride solution as described in C, not to specimens exposed to chloride ions during cyclic wetting and drying.

Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss asm individual project needs and testing response times. Use The apparent chloride diffusion coefficient is used to estimate chloride penetration into cementitious mixtures that are in a saturated condition.
Instructions The sample specimens may be cores, cylinders, or cubes. Client must specify the exposure age, water cementitious ratio and if a pozzolan or slag has been used as it is required to modify the depth intervals as specified in C156 C’s Recommended Depth Interval Table.
The diffusion of ionic species in concrete occurs within the fluid-filled pores, cracks and void spaces. If you need more info or have any questions, please note the Lab ID number and contact us at:.
